Abstract : This is a report of an occupational survey of the Diagnostic Imaging (AFSC 4R0X1/A/B/C) career ladder conducted by the Air Force Occupational Measurement Squadron (AFOMS). The current Diagnostic Imaging career ladder was created in 1996 with the merger of AFSC 4R0X1 (Radiology) and AFSC 4R0X2 (Nuclear Medicine). This is the first survey conducted on this AFSC since the merger. Survey data will be used to identify current utilization patterns among career ladder personnel and evaluate career ladder documents and training programs. The last OSR published for the AFSC 903X0 (Radiologic Career Ladder) was in September 1992. The last OSR which included Nuclear Medicine was a combined AFSC 903X0, 904X0, 909X0 (Radiologic, Medical Laboratory and Nuclear Medicine) study published in December 1978.
